I think that 1) the program "cvt" is useful for getting the details right ---- $ cvt 3840 2160 30 # 3840x2160 29.98 Hz (CVT) hsync: 65.96 kHz; pclk: 338.75 MHz Modeline "3840x2160_30.00" 338.75 3840 4080 4488 5136 2160 2163 2168 2200 -hsync +vsync ---- 2) you can use that almost verbatim to assign this with xrandr, rather than rebuilding the module: $ xrandr --newmode "3840x2160_30.00" 338.75 3840 4080 4488 5136 2160 2163 2168 2200 -hsync +vsync and then add that mode for the output (say VGA-2): $ xrandr --output VGA-2 --addmode 3840x2160_30.00 and then set that as the current mode for the output: $ xrandr --output VGA-2 --mode 3840x2160_30.00 regards, Ralph. _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
